BENCH-VISE.

SPECIFICATION forming part of Letters Patent No. 572,367, dated December1, 1896.

Application filed October 23, 1895. Serial No. 566,651 (No model.)

To otZZ whom, it may concern:

Be it known that we, JOHN F. PARKER and CALVIN M. BENNETT, citizens ofthe United States of America, residing at Portland, in the county ofCumberland and State of Maine, have invented certain new and usefulImprovements in Bench-Vises; and we do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

Our invention relates to improvements in bench-Vises, and especially tothat class of Vises having two movable jaws, one of which is capable ofbeing swiveled, so as to fit any desired bevel on the work to beinserted between the jaws.

It consists in a novel way of attaching the vise to the bench so that itmay be swung in any desired position of means for raising and loweringthe same so that it may be higher or lower than the bench, as desired;novel means for locking the vise when it is in the desired position, andalso in novel means of attaching, adj ustin g, and moving theclamping-jaws, and in certain other details of construction, which willbe hereinafter more fully set forth and specifically claimed."

In the drawings herewith accompanying and forming a part of thisapplication, Figure 1 is a vertical section of our improved device. Fig.2 is an end elevation of the same. Fig. 3 is a top plan view of thesame, dotted lines showing the adjustability of the clampingfaces. Figs.4, 5, 6, 7, and 8 are detailviews of the differentparts used in theconstruction of the vise; and Fig. 9 is a perspective view with a partof the bed of the vise broken away, showing means used for holding thevise away from or close to the bench.

Same letters refer to like parts.

In said drawings, A represents a suitable bench, to which is pivotallyattached, by a single or double yoke B, bracket 0, which sustains thebed of the vise. Adapted to extend through sockets D in the yoke is arod E, threaded, as at F, and having on its lower extremity a suitablehandle or wheel G. Said rod E also extends through thesustainingbrackets of the vise, the lower extremity of which is providedwith a threaded socket, so that when the handle is turned one way or theother by the thread in the socket in the bracket engaging the thread onthe rod E the vise-bracket is raised and lowered as desired. Adaptedalso to fit into sockets H in the yoke and vise-bracket is a rod I,having pivoted on its lower extremity a lever J, provided with acam-surface K, by which, when the lever is brought into action and thecam-surface is forced against the bottom of the vise-bracket and yoke,the vise is held firmly, thereby preventing it from moving on the rod 1.

Attached to the yoke B, as described, is a box L, which constitutes thebed of the vise. Said box is hollowed out and provided With a guide M tokeep the rod N in position. Said rod N is provided on a portion of itscircumference with ratchet-teeth O. Pivotally attached to the bed of thevise by means of an ear P is a pawl Q, adapted to engage theratchet-teeth on the portion of the circumference on the rod N. Theouter extremity of said rod N is provided with threads R. Said rod N isalso provided with astop S, as shown in Fig. 4. Attached to said rod atits threaded portion by means of the nut and screw T is a clamping-jawU, which constitutes the outer clamping-jaw of the vise.

Pivotally attached to the plate V by means of the pin W is the otherclamping-face X of the vise. In'order to prevent this jaw fromdisplacement when pressure is brought upon it, we provide the bed of thevise with sockets to and a pin Z), which is inserted through theclamping-jaw and the plate upon which it is mounted into sockets a. Inorder to adjust the clamping-jaw X at an angle requisite to receive thework, the pin 1) is removed from its socket c in the clamping-jaw andthe jaw X is then adjusted at the proper angle, the pin 1) beinginsertedbehind the plate, as shown at d in dotted lines in Fig. 1. Inorder to move the outer jaw U, the workman has only to turn the pivotedhandle 6 a sufficient distance so as to throw the ratchet-teeth 0 out ofengagement with the pawl Qthat is, until the stop S bears against theconfining-Wall of the vise-bed. Then the rod N may be pulled out orpushed in, as desired, and the handle turned so that the pawl may oncemore engage the ratchet-teeth. Then turn the handle 6 so as to tightenthe thread. By this means the clamping-jaw is moved slightly 'cles, andthe vise isready for use.

a rod g, adapted to slide in the socket h in the ear i, attached to thebed of the bench. Iivotally attached to said ear 2' is a leverj, havinga cam-surface Kthereon. It will be seen that when the cam-lever j ispressed down it will force the rod g against one of the edges in the eari and hold it firmly in position, and that when the lever is loosenedand the pressure removed from the rod gthe vise may-bemoved toward'oraway'from the bench, the rod 9 being allowed to slide in the socket 7bin "the ear 1'. Then the vise has been adjusted at a properdistance fromthe bench, the lever j is tightened and then'the rodg is forced againstthe upper edge inthe socket h, by means of which the bed of the vise isfirmly held in position and prevented from moving-away from'or towardthe bench.

The operation of our improved vise is as follows: When the workmanwishes to insert any article between the clamping-jaws, especially'ifthe end of the article is'cut on any size and length of the articlesrequire, inserts the pm I), as shown in dotted lines at (Z in 'Fig. 1,then forces the rod and clamping-jaw U inwardly until the clamping-jawbears against the outer extremity of the work, turns the handle 6 sothat the ratchet-teeth canbe brought into engagement with the pawl, thenturns the handle sufficiently to bring the clamping-s urfaces firmly upagainst the arti- Should the work be of'such a kind as to require thevise to be raised or lowered more than is ordinarily needed, the workmanhas only to turnthe handle G on the rod E. This, owing 'tothe threads onthe rod engaging the threads in the socket of the vise-brackets, willenable thevise to be raised and lowered as the workman desires. approachthe work from a different side in- Should the workman desire to ever wayhe wishes it, the vise moving 011 the yokes B. The levers arethen placedin position and the vise is 'rigidly'held in position.

WVe do not wish to limit ourselves to the specific form described forattachingour vise to the bench or for holding it away from or close tothe bench. WVell-known mechanical equivalents can be used foraccomplishing the same result without materially altering or "changingthe invention.

Having thus described our invention and its use, we claim-- 1. In abench-vise the combination of two clamping-jaws one of which beingadjustable at any an gle,'means for holding said clampingjaws inposition, means for pivotally attaching the same to a rigid object,means for raisin g and lowering the vise, means for swinging the viseand holding it in any desired position, substantially as and for thepurposes set forth.

2. In a bench-vise the combination of a bed provided with socketstherein of two movable clamping-faces the one adapted to slide on saidbed and adaptedto beset at any'angle the other mounted'upon a rodthreaded part way of its length and'havin g on a portion of itscircumference ratchet-teeth adapted to engage a pawl pivotally attachedto "the bed of the vise, meansfor throwing said ratchetteeth and pawlout of engagement and means for moving said clamping-faces,substantially as and for the purposes set forth.

3. In a bench-vise in combination a bed two adjustable clamping-jaws oneor more yokes pivotally attached to the vise and rigid object, a rodextending from the rear of the bed through a slotted plate attached tothe rigid object, a cam-lever-attached to said slotted plate and adaptedto hold said rod rigidly in place, and means for raising and loweringthe bed, substantially as and for the purposes set forth.

4. In a bench-vise in combination,'a suitable bed providedwith sockets,two adjustable clamping-faces moving on said bed, said bed beingpivotally connected by means of a bracket and yoke'to a suitable rigidobject,

an ear attached to the rigid object and having a slot therein, a rodpivotally attached to the bed of the vise and adapted to slide in theslot in said ear, and means for holding said rod rigidly in position,substantially as and for the purposes set forth.
